Table 4.
The difference of and the correlations between CICCP and TIPP in the records with subjects in a calm state.
| Count of identical values in LP∗ | Record numbers | Percentage of difference between CICCP and TIPP ≤2 mmHg (%) | Spearman's rank correlation | |
|---|---|---|---|---|
| Rho | p value | |||
| ≥3 | 1185 | 90.0 | 0.733 | <0.001 |
| ≥4 | 888 | 89.3 | 0.694 | <0.001 |
| ≥5 | 672 | 86.3 | 0.701 | <0.001 |
| ≥6 | 517 | 88.6 | 0.706 | <0.001 |
∗The data count of the longest episode (LP) in which each of CICCP and TIPP had an individual series of identical values. Series of CICCP and TIPP were included in the analysis if their counts of identical values in LP were equal to or greater than the number listed in the column. CICCP, pressure measured by central inserted central catheter; TIPP, pressure measured by totally implanted port; LP, longest period.
